About Selenium:Thought work is a global IT outsourcing company which focuses on Agile software development. The company has contributed many open source product and one of the product is called Selenium.

Selenium Contributors

The story of Selenium starts at 2004 in chicago by Jason Huggin buildings core made as “Javascript Test Runner”. They created this core for the testing of an internal time & expenses application written in (python, plone). Automatic testing of any applications is core to ThoughtWork's style, given the Agile leanings of this consultancy. He has help from Paul Gross and Jie Tina Wang. For them, this was a day job.

Later Jason started giving demo to other colleague in his team and people got impressed by the testing framework & he got very good feedback for this work.

Soon after in 2004 fellow ThoughtWorker Paul Hammant saw the demo, and started discussions about the open sourcing of selenium, as well as defining a “driven” mode of Selenium where you'd get to use selenium over the wire from a language of your choice, that would get around the 'same origin policy'. Another colleague Aslak Hellesoy, experimented with different ideas for the 'Server' piece, including page rewriting to get around the same origin policy. Paul wrote the original server piece in Java and Aslak and obie fernandez ported that the client driver to Ruby setting the foundation for drivers in yet more languages.

Outside of ThoughtWork:At Bea, Dan Fabulich and Nelson Sproul came to the conclusion that the driver/server to browser architecture was not the most useful or flexible, so forked the driver coder and crafted that into a standalone server that leveraged and bundled MortBay's Jetty as a web-proxy. When the code was merged back it became known as "Selenium Remote Control" and the old driven codeline and capability was retired.

Selenium-IDE: Made in Japan:Shinya Kasataniin Japan became interested in Selenium, and realised that he could wrap the core code into an IDE module into the Firefox browser, and be able to record tests as well as play them back in the same plugin. This tool, turned out an eye opener in more ways that was originally thought as it is not bound to the same origin policy.

What is selenium?

Selenium is one of the most powerful open source automation tool for web application testing(even we can say acceptance testing for web application). This tool is primarily developed in Java Script and browser technologies such as DHTML and Frames and hence supports all the major browsers on all the platforms. For example, you can have your automation scripts written for Firefox on Windows and run them on Firefox in Mac. Most of the time, you will not need to change your scripts for them to work on Mac. It is more suited for the agile methodology of coding and testing. User can customize the selenium tool based on their requirement(code is available for the user). In terms of coverage for platform and browser, Selenium is probably one of the best tool available in the market for web applications. Selenium is an automate web application testing across many platforms . Especially for Compatibility and functional testing.

Advantage of selenium:1. Opensource tool2. No licensing cost associated with it3. Customize according to our requirement

Disadvantage of selenium:1. we cannot be assured of any add-ins which would be required if selenium fails to recognize

objects2. Also Support provided for Selenium would be very less ( Incase of QTP, Mercury provides

standard solutions and supports to issues)

Variants of Selenium:There are four variants of Selenium, which can be used in isolation or in combination to create complete automation suite for your web applications.

• Selenium IDE • Selenium Core • Selenium Remote Control

• Selenium Grid

General Functional Testing:Functional testing tool with its powerful set of features allows automated GUI testing in minutes. Listed below are some of the features of functional testing.



Scripting capabilities

Portability

Validation & Verification

Playback Options

Reporting Capabilities

AJAX Testing

Scripting Capabilities Simplified Script Creation – In selenium, the default script is in html and it is the most common

scripting language used among peoples.

• Keyword driven testing • Standard Scripting Language allows you to easily create/update scripts without much

programming knowledge. • Object Repository is not available in selenium but it is one of the features of all Functional

testing tool.• Data driven Testing enables you to perform functional testing in different scenarios by just

changing the test data in an external data source. Selenium supports Data driven testing.• Unicode supports allows you to test multi-language deployments of your applications. • Supports pattern-matching capabilities to improve test script reuse, if application changes

frequently.

Portability :• Allows you to record scripts in Windows and replay it in Linux without re-creating the scripts. • Browser Abstraction Layer allows scripts recorded in one browser to be replayed in all other

supported browsers. • Runtime locale option lets you to simultaneously test all language versions of your application

with a single script.

Validation and Verification• Rich Library of Built in function added using the Function Generator tool. This helps you to

construct function calls for specific testing requirements which include: In selenium, user has to create Built in function for their testing.

• Checkpoints that include Text, GUI, XML, File and Database enable thorough validation of your web applications/web sites. In selenium, there is a similar thing for checkpoint called verify or asset. But user can't able to check for images/bitmap. If user wants to check for database then they have to create a database connection with JavaScript and put it in user-extensions.js but not sure about creating check points in the database. I left the choice to the user.



Playback Options • Automatic/Customizable Error Recovery for unattended testing to handle unexpected window,

like an ASSERT box, pop- ups, etc. But automatic error recovery for unattended testing is not available for selenium but user can write his/her own scripts to handle this.

• Playback Synchronization to handle the variation in time the application takes to load a new page. Ex: In selenium ClickAndWait is a command which will wait for the page to load and start executing the next command.

• Option to chain scripts for controlling the order of script execution. In selenium core, we can do the order of execution and if user wish he can execute everything as a batch file.

• Multiple Play back options that enables testers to debug test errors while creating and maintaining test scripts. Selenium supports multiple play back options.

• Allows execution of individual and/or groups of tests from one or many workstations. • Provision for command-line invocation allows invocation from batch files or scheduling

utilities.

Reporting Capabilities • Clear and Powerful Reports are provided to indicate the status of the test execution. • Hyperlinks or color coding(RED color for failure) allow easy navigation through the report.

This helps you to quickly identify application failures and clearly assess application quality.

Supported Environments: Internet Explorer 6, Firefox 1.5.x and Mozilla 1.7.x, Windows XP, 2000 and Linux.

Web Functional Resources :

Compatibility Testing:

Today organizations trying to automate their web applications/web sites are looking for a uniform testing solution. This will help them to reuse test scripts to test it in different platforms/different browsers/different languages/different databases/different servers. The common testing issues are

Different Browsers

Different Browser Versions

Different Computer Types

Different Screen Sizes

Different Font Sizes

HTML Errors

Browser Bugs



Different Browsers:

Your Web browser is a translation device. It takes a document written in the HTML language and translates it into a formatted Web page. The result of this translation is a little like giving two human translators a sentence written in French and asking them to translate it into English. Both will get the meaning across, but may not use the same words to do so.

The basic rules for translating HTML documents are established by the World Wide Web consortium,which publishes the official HTML standards. Though they defined standards, they missed out by providing certain information.

For example: HTML standards says that if you are using table, then CellSpacing(spaces allocated to each cell) should be defined in your code. But the standards didn't mention what is the default cellspacing. So developers defining their own value for Cellspacing. If the webdevelopers is not mentioning any value for cellspacing then the browser will take the default browser's value. So twobrowsers may use different amounts of white space in your table

In addition, the HTML standards usually run ahead of what the browsers support. No browser as yetsupports 100% of the HTML Version 5 standard, but some browsers come closer than others. Overthe past few years Internet Explorer has done a much better job of this than Netscape Navigator,though Opera has done arguably the best job.

latest HTML tags isn't universal, you could be building your pages with parts of the language that not all browsers understand. In that case the browser will ignore that part of your page it can't translate, and the way your page displays will be affected.

Different Browser Versions

The major difference between two versions of the same browser is their support for newer portionsof the HTML language. A new browser is generally better at displaying Web pages than an old one.

Suppose if I create a webpage using latest version of html standards and browsers(ex I.E 7) but the client (user) doesn't using the latest version of browser then they can't able to view the browser page properly.

A good rule of thumb is to design your pages to work for the last two versions of the major browsers.

Different Computer Types

The Macintosh is still used by 12% of computer users, and has a very loyal following among graphicdesigners and publishers. In theory, if you view your page on both a PC and a Mac using the sameversion of the same browser, it should display the same, right?In practice that's rarely the case. There are three reasons for this:



• Font Availability: When you tell your Web page to use a particular typeface, such as "Arial,"you may not always get the font you want. Fonts are a computer resource, and not allcomputers have the same fonts as your computer. That's true even between different PCs, butit's especially true between the PC and the Mac. If the typeface of your page suddenlychanges between these computers, you've probably used a font that isn't available on bothcomputer types.• Font Size: The Mac will generally render your typeface in a smaller pixel size than the PCwill. That's especially true if you use the FONT tag to set your type size, since this tag usesabstract units to define size. You can avoid this problem is you use Cascading Style Sheets toset your font size in pixels. ac.• Internet Explorer: Microsoft outsources the development of Internet Explorer for the Mac,and so to a large extent this is a different browser from the PC version. In particular, the Macversion of Internet Explorer is prone to quirks and bugs that you won't see in the PC version.If you check your Web page under only one browser on the Mac, do so under Internet

Explorer!

Different Screen Sizes

If you don't test your pages using different screen resolutions, your page may be stretched to fit a large screen, or be cropped to fit a small screen.

Many experienced Web designers use HTML tables to control their page layout, yet they design theirpages on large, 1024x768 pixel screens. When these pages are displayed on smaller computerscreens, the browser may not be able to fit all the content onto the screen. In these cases, the contentwill scroll of the right of the page. While this may not sound like much of a problem, users hatescrolling left and right to view a page.

This problem should be easy to avoid, yet a surprising number of otherwise well-designed Web sitesdon't fit within the standard 800-pixel PC computer screen. This is especially a problem for pagesbuilt by graphic artists using a Macintosh, whose standard screen size is 1024x768. Many designersforget that designing for an 800-pixel screen means using roughly a 750-pixel layout.

Many less experienced Webmasters design their pages without tables, or dimension their tables to fit100% of the screen width. If you've built your Web page this way on a computer with an 800-pixelscreen, you may be surprised how your page is stretched to fit a larger screen. Text and graphics thatwere adjacent on your smaller screen may not be so on a large screen.

To avoid this, wrap the content of your page inside a single, large, one-cell table. Set the width of thistable to be about 560-pixels, if you're designing for a 600 pixels layout, or 750-pixels if you'redesigning for an 800 pixel layout.Because the majority of Internet users have a screen resolution of 800 pixels or less, it's a bad idea to design your site for a larger screen.

Different Font Sizes



Most browsers allow users to customize their default font size. Many users who work on computersall day do this to reduce eye strain. As a result, user preferences may cause the typeface that you usedto design your Web page to increase as much as 50% larger in a user's browser. This increase in fontsize can hurt many carefully-planned page designs.

Everyone is eager to start testing the application in selenium. Now let us get to know about SeleniumIDE.

Selenium IDE:

Installation instruction of Selenium IDE:

Prerequisites:Mozilla Firefox – browser minimum version 1.5

Step1: Download the mozilla firefox from the following site:

http://www.mozilla.org/download.html


http://www.mozilla.org/download.html


Step 2: Go to the latest version of Firefox page, click the download button. Here we are using version3 of mozilla.

Step 2: Sometimes, browser may block the sites, Unblock and allow the sites for download.



Step 3:Mozilla Firefox start adding the extensions in the Mozilla browser



Step 4: Inorder to activate the Selenium IDE , restart the browser.



Step 5: Continue,...



Step 7: Now Selenium IDE has been successfully added into the Mozilla Firefox browser.

Step 8:

Open the Mozilla firefox|-------------Click the Tools

|-----------------Selenium IDE

By default, selenium starts in recording mode.



Congratulation! You successfully installed Selenium IDE.



Tutorial on Selenium IDE:

Introduction about Selenium IDE:

Selenium IDE is a Firefox plug in, which includes the entire Selenium Core,allows you to record, play back, edit, and debug tests in browser. It provides the simplest introduction to Selenium and is highly recommended for beginners.

Selenium IDE is the only flavor of Selenium which allows you to record user action on browser window. It can also record user actions in most of the popular languages like Java, C#, Perl, Ruby etc. This eliminates the need of learning new vendor scripting language. However to run them in an automated fashion you need to use Selenium Remote Control.

Selenium is a powerful tool for controlling, automating, or testing websites. If there is any repetitive tasks or predictable task that you are always doing in browsers that you can handle it in Selenium IDE.

So if you are excited about the tool, Lets start playing with Selenium IDE now. If installed properly, Selenium can be accessed from tool --> Selenium IDE in your browser tool bar. By default, Selenium IDE will open in Record mode.



Figure 1: Selenium IDE window

The four execution buttons on the top are:

• Run All Tests: Run every test in the test suite. • Run Selected Test: Click on one test in the test suite, then click here to run just that one test.

• Pause / Continue: While a test is running, press the Pause button to temporarily stop running commands. After you press Pause, you can press Continue to resume the test.



• Step: Click on a test in the test suite, then click on just one line of the test to set a "breakpoint." When the TestRunner reaches a breakpoint, it will automatically pause execution on that line. You may then press the Step button to run the next line of the test and pause again. You can also click on a breakpoint line to remove the breakpoint.

Figure 2:

In selenium IDE , user can do certain customization that will be available as a default settings.For that, click the Options tab in the menu bar, there you can able to see “Options” , click this “Options.



Selenium IDE options window will open. User can able to see two tab. 1. General tab2. Format tab

In general tab, you can change the setting like encoding format UTF-8 format into anyother format. By default Selenium IDE is available in UTF-8 (UTF-8 stands for Unicode Transformation Format-8. It is an octet (8-bit) lossless encoding of Unicode characters).

Default timeout value of the action is 30000 milliseconds. user can change according to their requirement



Similarly they can do other modification according to their wish. Most of the information are self explanatory.

It is not mandatory , user should know about all these data's. If we know, it's additional information to the user , merely we can say it as GK(general knowledge)



Option format list out the available language of the selenium. User can customize the format according to their requirement. Steps: choose the language,in the corresponding language format will be displayed in the RHS. Edit the default format and provide your own format to be appear in the language. The few are “Template”, “Command” entries. “regular expression” , “Header”, “Footer”, etc..,

Any way selenium default scripts is html(added javascript) and that is the script we are going to use it in selenium IDE. The reason for availability of other language is , user can get the scripts for Selenium Remote Control. In selenium RC, user has to write the scripts on their own, instead of writing they can get the scripts(with little modification) from Selenium IDE and execute it in Selenium RC.

Now let's create a sample script in Selenium IDE , so that the user will get to know about the usefulness of Selenium IDE well.

Step1: I am assuming that your home page is “www.google.co.in”

Open the mozilla firefox |----------------Click the Tools

|----------------Options

|---------------Selenium IDE

By default, Selenium IDE will open in record mode. No need to click the “Record” button. Minimize the Selenium IDE window.


http://www.google.co.in/


Step 2:Type “Picasa Web album” in google,



Step 3: Now Google will list out the search result. Choose the Picasa webalbum which usually appears in the first of search. Click and move to the login page.



Step 4: This is the login page of the picasa web album. If you are having gmail account, then use the same username and password to login. If you doesn't have then try to create for this selenium test.



Step 5: Now login to the picasa webalbum. Whenever you login to any web page using your account, the next page is the welcome page for the user. Most of the website, display the username or else useraccount email id to display. In this example, it is displaying “[email protected]”. Next click the “signout” link.

Now open the seleniumIDE, choose either “table” tab or “source” tab. In table tab, the steps has been generated in a table format. If you click the source tab, then the html + javascript coding has been generated.


mailto:[email protected]


If the user wants to see the generated scripts in other programming/scripting language, Go to Option → format-> choose any other language. Source tab automatically update the scripts in the corresponding chosen language. Other programming scripts cannot be run in Selenium IDE,user has to use selenium RC(remote control) to execute the scripts. The purpose of this is, user can record and get the scripts for selenium RC not for selenium IDE. Here we are going to use HTML only.



Now user can save the scripts in the desired location of the computer. Now click the run button and start executing the scripts. This will give an assurance to the user, the generated scripts is running properly. Later they can customize the script for validation, robustness, etc..,



Whenever Selenium execute, it will highlight the executing line in “Yellow” color , if the line executed successfully then the color will change to “Green” else failed line in “Red” color.

There are many things to check in webpage like text appeared or not, image displaying properly in different browser or not, button enabled or not etc..,

Here in our example, we are going to check , after login the page is moving to welcome page. In welcome page, is the web page displaying the username (username or email id of the login) properly or not.

Now let's modify or tweak our generated scripts little bit.

“Assert text present” is the inbuilt command present in Selenium IDE. This command will check whether the webpage is having the text or not.



After saving the scripts, user can open the scripts either in notepad or else in wordpad to view the scripts.



After asserting the scripts, now try to run the scripts. The scripts will execute successfully. If you give different username, the scripts will fail.

Congratulation!!! Now you can able to record and do testing in Selenium IDE.



Now we will see certain things in little advance. 1. The default commands generated by selenium when you are browsing the page as a normal user should be modified to make the test more robust and to add test cases to it.

For ex:

Replace all click commands by clickAndWait. click simply clicks the specified link andgoes on to execute the next command without waiting. On the other hand clickAndWait waits for the new page to loaded before executing the next command. clickAndWait should be used to make more robust test cases.

Insert assertTextNotPresent command after each clickAndWait command to confirm a text must not be present in the browsed page.

Use assertTextPresent command to confirm a text must be present in the browsed page.

Let's see the code present in Selenium IDE table tab.



When you look at the table , there are 3 columns

1. command2. target3. value

This is actually crux of selenium work.

Command Target ValueCommand Target &nbsp (no value) , relevant valueAssertion Expected Actual

A command is what tells Selenium what to do. Selenium commands come in three 'flavors': Actions,Accessors and Assertions. Each command call is one line in the test table of the form.

Command Target Value

Actions: Actions are commands that generally manipulate the state of the application. They do things

like "click this link" and "select that option". If an Action fails, or has an error, the execution of the current test is stopped.

Many Actions can be called with the "AndWait" suffix, e.g. "clickAndWait". This suffix tells Seleniumthat the action will cause the browser to make a call to the server, and that Selenium should wait for anew page to load.

Accessors:Accessors examine the state of the application and store the results in variables, e.g.

"storeTitle". They are also used to automatically generate Assertions.

Assertions:

Assertions are like Accessors, but they verify that the state of the application conforms to what isexpected. Examples include "make sure the page title is X" and "verify that this checkbox is checked".

All Selenium Assertions can be used in 3 modes

1. assert2. verify3. waitfor



For example, you can "assertText", "verifyText" and "waitForText". When an "assert" fails, the test is aborted. When a "verify" fails, the test will continue execution, logging the failure. This allows a single "assert" to ensure that the application is on the correct page, followed by a bunch of "verify" assertions to test form field values, labels, etc.

"waitFor" commands wait for some condition to become true (which can be useful for testing Ajaxapplications). They will succeed immediately if the condition is already true. However, they will failand halt the test if the condition does not become true within the current timeout setting (see thesetTimeout action below).

TARGET:

Element Locators tell Selenium which HTML element a command refers to. The format of a locator is:

locatorType =argument

selenium supports the following strategies for locating element:

1. id 2. name3. xpath4. dom5. identifier6. link7. css

id and name:Whenever you open any web page, right click and try to view the source code. You will come

across id or name for the web object.Based on this , user can uniquely identify the webobjects such as textbox, listbox, radio button

etc.., Each will be having it's own id , name.

In our example: we used google as the webpage. “q” is the name for the “google textbox”. That is the

reason,first line of our scrips had “q” as the target and “Picasaweb album “ as the value we typed in the text box



xpath:

To put it in a simple way, xpath is like hierarchy or the order used to identify any object.

In out Example:

Link:Select the link (anchor) element which contains text matching the specified

pattern.

• link=The link text

CSS:

Select the element using css selectors.

css=a[href="#id3"]

DOM:

dom=javascriptExpression.

User can find an element by evaluating the specified string.

dom=document.forms['myForm'].myDropdown• dom=document.images[56]• dom=function foo() { return document.links[1]; }; foo();

After reading all these , few tester would have an idea to drop down to use selenium. The reason might be, more of codes and finding the objects(element) unique name, id or else css name, etc..,

No worries guys, No need to break your head to find it out.

There is a tool called “FIREBUG”. Using this tool, user can able to identify any object's id, name,xpath, CSS, dom , link, etc..,

Now let's look on to the firebug installation and continue our selenium IDE.



FIREBUG:

Firebug is add on available for Mozilla Firefox.

Step1:

User can get it in the following link.

https://addons.mozilla.org/en-US/firefox/addon/1843


https://addons.mozilla.org/en-US/firefox/addon/1843


Step 2:

Sometimes software will be blocked by the browser , So click and allow for downloading and installation.



Step 3:After installing the add-on , restart the browser.



Step 4: Installation has been successfully done. Click the tools , firebug and open firebug.



Step 5: Now user can see the Firebug window in the lower part of the browser. Click the inspect , then wherever you are moving the corresponding coding will be displayed in the console of firebug.

Using this user can find the target value and make the testcases more robust.



Advantages:• It is a Freeware• Simple, Easy to install, Easy to work• Selenium IDE is the only flavor of Selenium which allows you to record user action on browser

window• Can also record user actions in most of the popular languages like Java, C#, Perl, Ruby• It will not record any operation that you do on your computer apart from the events on Firefox

browser window• During recording if you right click on any element it will show all the selenium commands

available• You can also edit existing command, by selecting it and editing on the boxes available• You can also insert/delete commands by choosing appropriate option after right clicking• Choose appropriate run option - i.e walk, run or test runner and review your results

Disadvantages: 1. Limitation in terms of browser support (It runs only in Mozilla)2. We can’t run recorded script if it is converted to Java, C#, Ruby etc.3. Not allowed to write manual scripts like conditions and Loops for Data Driven Testing4. There is no option to verify images.

Congratulation Reader!!! Now you can start exploring SeleniumIDE on your own and do testing. The content given above is just a glimpse not for the expert level of SeleniumIDE. The more user practicing the scripts in real time will give more idea of using the Selenium IDE. “ALL THE BEST” for it.



SELENIUM CORE:Selenium Core requires a web server and the Selenium Core zip file. Here I am using Apache as

my web server. User can even use other web server (IIS, Tomcat, etc..,)for selenium core

Installation instruction for Selenium Core:

1. Web server-Apache2. Selenium -Core

1. Download and install apache2.2.4(download the latest version of

Click the following link and download the Apache2.2.4:

http://archive.apache.org/dist/httpd/binaries/win32/

Search for the following msi( windows installer)

apache_2.2.4-win32-x86-no_ssl.msi


http://archive.apache.org/dist/httpd/binaries/win32/


Step 1:

Now we're ready to install. “Double-click” the installer.

Step 2:

Click the “next” button in the Installation Wizard



Step 3: Accept the License agreement and click the “next” button

Step 4:

Provide the Server information details in the window.Domain Name : ITCINFOTECH.COMServer Name : The computer nameAdministrator’s Email id: Provide administrator email id. (If any error or problem in application you will get the information “asking the user to contact the administrator” For Ex: “Please contact [email protected]



Step 5:Choose "Custom" and press "Next".



Step 6: On the following screen you will see the default path of Apache to installs. Click the "Change..." , and choose the D:\ProgramFiles folder (or whatever other name you chose) you made when you created the directory structure above. Click "Next".

Step 7: Continuation…



Step 8:Create a folder “Apache Software Foundation\Apache2.2”.The directory structure is like this: D:\ProgramFiles\Apache Software Foundation\Apache2.2\

Step 9:Click the “install” button and proceed further for installation.



Step 10:

You can see the status of Installation status in the Installation wizard.

Step 11:Once the installation has been completed, you will be getting the following window. Click finish. Congratulation, apache 2.2.4 installation has been successfully finished.



Step 12:

Let's make sure it worked. Go to your programs folder in the Start menu and find the Apache HTTP Server folder. Go to the Control Apache Server folder, and start Apache

If you installed Apache as a service, you can also start it by double-clicking on the Apache Service

Monitor tray icon (which looks like: ) and pressing the "Start" button in the window that appears. If you did not install it as a service, you will see a blank command prompt window appear while Apache is running. This is normal.

The first time you run Apache, you will probably see a security warning pop up:



This is because windows has detected that Apache is opening a port on your computer, and it is checking with you about whether it should let Apache continue. Click the "Unblock" button to allow Apache to function.

Now, let's open up a web browser and make sure Apache is running. Type in the name of your server (e.g. local host, or your domain name or IP address) in the location bar of the browser.

http://localhost/

or

http://localhost:8080/


http://localhost:8080/

http://localhost/


If so, you're ready to move on. If not, something is wrong. It is hard to be sure what, but it might help to ask for assistance in the ERT forum. Otherwise, your best bet is to uninstall Apache and try again.

Before proceeding to forum, check whether the following fields are having correct data and also these are the lines where user can modify.

Download Selenium Core:

Click the following link to download the Selenium Core. Try to download the latest version. Note: The latest version always available at the top of the page.

http://selenium-core.openqa.org/download.jsp


http://selenium-core.openqa.org/download.jsp


Step 2:Downloading the selenium core



Step 3:

Unzip the selenium-core0.8.3 then copy the extracted one to the root directory of Apache2.2.4(“D:\ProgramFiles\ApacheSoftwareFoundation\apache2.2.4\”Selenium-core0.8.3)

Now , open the Internet Explorer (any browser such as firefox , netscape, etc...), type the following

http://localhost/


http://localhost/


User can able to see the Selenium-core folder available in the webpage. Click it.

Now the page will be having the Selenium core related information. By default, selenium core comes with an example. Using selenium core, user can do Acceptance and Unit testing. If you click the link such as Selenium Test runner, then you will move the selenium Testing home page.



User will be getting the following page. The page has been classified into Test suite, Current test, control panel.Test suite : The testsuite and individual test will be available in this locationControl panel:There are many options available in control panel. They are Runall , Run individual testcases, step in , pause, log file, dom viewer etc.., Once the testcases has been run, test summary will be available for the user.Current Test:In this location, user can view the steps of the test cases. When you start running, each line of the test cases will be executed and the execution line will be in yellow color , the passed and the failed test cases will automatically get the green and red color.



The application under test



I hope the user learnt the overview of the Selenium Core. Now let's start using the selenium Core with some practical examples.

Steps: 1 . open the Internet explorer

2. type http://localhost/3. choose the seleniumcore-0.8.34. Now user will be getting the selenium list of testing type5. choose the first option “Selenium TestRunner”6. user will be getting selenium functional testrunner page7. LHS, test suite is available and the default values of it is “../tests/TestSuite.html”, below it there

is a “GO” button. Click the “GO” button8. Now user can see, list of Testsuite. Choosing any of the testsuite , corresponding test will be

available in the middle tab.9. First time you are doing testing in selenium core , so I prefer user to choose RunAll tests button.


http://localhost/


10. Now wait and watch. (yellow is for executing test cases , red is for failed testcases, green is for passed testcases)

11. After 3 minutes, the entire test suite run and user will be getting the status of the ran testsuite.

Now the user ran the available scripts. But as a user we should know how to add our scripts in the LHS testsuite and trying to execute it.

Before adding scripts we should know certain things.First of all Selenium core requires the application under test should be in the same pc. We can't able to do other webtesting. For example: if we try to do testing, we will be getting “Permission denied”. So we need the application to be in the server.

So I couldn't able to give a sample application. But I will give an overall idea of how to add your testsuite in Testsuite window.



Let's learn how to add our testsuite in the LHS window.

The default testsuites are available in the following location,“D:\ProgramFiles\ApacheSoftwareFoundation\Apache2.2\htdocs\selenium-core-0.8.3\tests”

Open the tests folder, search for a “TestSuite.html” file. Open the file(TestSuite.html) either in wordpad or notepad.

End of the html coding, you can able to see the following code,

<tr><td><a href="./dogfood/TestFailures.html">DogfoodTestFailures</a></td></tr>

The meaning of the above code is, open a folder called “dogfood” and search for TestFailures.html When the user click “DogfoodTestFailures”, it will try to open the file TestFailures.html from the folder dogfood.

Now we will give our own name for the sample testsuite. For example: “MyScript”

Add the following line next to the “DogfoodTestFailures”

<tr><td><a href="./sample/TestFailures.html">MyScript</a></td></tr>

Now create a folder called “sample” in the following location,

“D:\ProgramFiles\ApacheSoftwareFoundation\Apache2.2\htdocs\selenium-core-0.8.3\tests\sample”

Right now we don't have our own application need to test. So we will take the provided sample application “dogfood”. Copy all the content (folder and files) from the D:\ProgramFiles\ApacheSoftwareFoundation\Apache2.2\htdocs\selenium-”core-0.8.3\tests\dogfood” and paste it in sample folder.

Now we are ready with the application need to be tested.



Step 1: Open the Internet Explorer – type http://localhost/

Step 2: choose “selenium-core-0.8.3”

Step 3: Select the “Selenium Test Runner”

Step 4: In LHS(Testsuite) window, you can able to see the text box having “../tests/TestSuite.html”

Step 5: Click the “Go”button

Step 6: Now you can able to see list of “Testsuite”, at the end “MyScript” the one which we created in the Testsuite.html file. Select the testsuite.

Step 7: Click the Run button in the control panel

Step 8: The testcases will be executed and the result will be displayed in the control panel.


http://localhost/


User cannot do testing on cross-site. If the user prefers to use Seleniumcore then they should have the application under test in the same machine. If you wants to do cross site testing or web application then you have to go for SeleniumIDE or Selenium Remote control.

Now we will end up the seleniumcore here. Now let's proceed with the SeleniumRemote control.



Selenium Remote Control:

Installing JDK latest version:Step 1: Go to the following link, try to download the latest version of JDK(right now 6.0 is the latest version but in my screenshot , I used the older version , so get confused with it)

http://java.sun.com/javase/downloads/index.jsp


http://java.sun.com/javase/downloads/index.jsp


Step 2: Accept the license agreement appearing in the next page of download.Note: Before moving to this page, user has to choose the platform and language option.Platform: Windows Language: Multilanguage

Step 3: Choose the offline installation , save dialog box will open. Save the executable file in the desired location.



Step 1: Run the installer. Don’t click cancel



Step 2: Accept the License Agreement and click the next button

Step 3: Choose a location for installation. click the next button.



Step 4: Installation are being in Progress

Step 5: Run Time Environment – Custom Setup. Click the next button to continue.



Step 6: Browser Registration. Click the next button

Step 7 : Installation is in Progress



Step 8: Successfully Installed



Checking the java installation:Go to command prompt and type javac. If it successfully installed, you will be getting the information about the java.



Step 9: See the java home and path in the system properties

If the Java class path is not set properly, then you need to set manually. Go to command prompt, type the following,

set JAVA_HOME=C:\Program Files\Java\jdk1.5.0_08set PATH=%PATH%;%JAVA_HOME%\bin

or else

Right click on My Computer, click system properties,

5. go to Advanced



6. Environment Variables7. Click new and set the path.

set JAVA_HOME=C:\jdk1.5.0_08set PATH=%PATH%;%JAVA_HOME%\bin



Download the selenium Remote control from the following link.http://selenium-rc.openqa.org/download.jsp


http://selenium-rc.openqa.org/download.jsp


Extract the Selenium remote and paste in any directory(For convenience, I placed in D: drive). Now Open the selenium Remote control folder, you will be having the different client drivers.



Now that you have installed the Selenium files, you need to let windows know where to look if you run a selenium command. You do this by adding the Selenium directory to your environment path:

To add Selenium to your Windows environment take the following steps:

3. Click on Start4. Right Click on My Computer5. Click on Properties6. Click on the Advanced tab.7. Click on Environment Variables8. On the upper half there should be a Variable named PATH

1. If you located it, double click on it, and add this value at the end of what is already in “Variable value”:

;C:\selenium-remote-control-0.9.2\selenium-server-0.9.2\selenium-server.jar

Make sure you replace -0.9.2 with the version you downloaded

2. If you do not located it, do this:

1. Click on New

2. For Variable name: enter: PATH

3. For Variable value: enter:

C:\selenium-remote-control-0.9.2\selenium-server-0.9.2\selenium-server.jar

(Make sure you replace -0.9.2 with the version you downloaded)

4. Click on OK

9. Click on OK10. Click on OK

Now you have finished setting up the environment, the next step is to run a few selenium commands.



Ok now we are going to run some basic selenium commands from the command line.

To start off lets first open the command line window:

Click on StartClick on Run…Type in cmd

Now that the command line window is open lets try some basic Selenium commands as mentioned on the Selenium tutorial page

Once you've got Java installed and ready to go, you can start the Selenium Server from the command line like this:

java -jar selenium-server.jar -interactive

That will start the Selenium Server and allow you to type commands in the command window. After a number of log messages, you should see the following message:

Entering interactive mode... type Selenium commands here (e.g: cmd=open&1=http://www.yahoo.com)

Let's begin by using Selenium Server to open up a browser. If you're on Windows and want to run your Selenium commands using Internet Explorer, try typing this:

cmd=getNewBrowserSession&1=*iexplore&2=http://www.google.com

If you want to use Firefox, try this:

cmd=getNewBrowserSession&1=*firefox&2=http://www.google.com

You're running the "getNewBrowserSession" command, using the browser of your choice (*iexplore for Internet Explorer, *firefox for Firefox, or *opera for Opera), starting at www.google.com. Typing commands in this window automatically fires off HTTP web requests to the Selenium Server, requesting work to be done. (In non-interactive mode, you can use any automated tool you like to send these HTTP requests to the server, instead of typing them by hand.) When you press Enter, you'll see a message describing the request you just made:

---> Requesting http://localhost:4444/selenium-server/driver?cmd=getNewBrowserSession&1=*firefox&2=http://www.google.com

If all goes well, you should see a new browser window starting with the browser of your choice. Back in the Selenium Server command window, you should see the following message:

Got result: OK,260113 on session 260113

(If this doesn't happen, you may need to take a look at our fine Troubleshooting guide.)


http://wiki.openqa.org/display/SRC/Selenium+RC+FAQ


The first part of this message "Got result: OK" says that your request for work was successful. The second part of this message, the number, is a Session ID. The Session ID will be different every time you run the "getNewBrowserSession" command from the command line.

Let's try some more commands; let's do a Google search! We'll start by opening up the Google website. Type this in the Selenium Server command window, replacing the Session ID below with the number you got when you ran "getNewBrowserSession":

cmd=open&1=http://www.google.com/webhp&sessionId=260113

When this command finishes, your browser window should reveal google.com in the lower frame. (The /webhp makes sure we stay on www.google.com; otherwise, we might get redirected to a country-specific Google server, e.g., www.google.fr.) Don't forget that you need to replace the Session ID above with your own personal Session ID, the one you got when you ran the "getNewBrowserSession" command.

Now that Google is open, let's try typing something in the search box. Type this in the Selenium Server command window:

cmd=type&1=q&2=hello world&sessionId=260113

Again, don't forget to replace the Session ID with your own Session ID. If all goes to plan, you should see "hello world" in the search box for your Google search.

Now, let's do a search!

cmd=click&1=btnG&sessionId=260113

You should now see the results of your Google Search in your browser window. You can run dozens of Selenium commands to automate all manner of browsing tasks. For more information on particular commands, you can go look at the Selenium Core section at the Open QA website, or check out the reference materials available for any of our Client Drivers (Java, .NET, Perl, PHP, Python or Ruby).

The next thing we might want to do is read some information back out of the page... for example, let's retrieve the HTML title of the current page, like this:

cmd=getTitle&sessionId=260113

The browser will return the title of the HTML page we've loaded, like this:Got result: OK,hello world - Google Search on session 260113

That's enough Interactive Mode for now; let's move on to writing some code! But before we go, let's stop the browser we started. Type this command in the Selenium Server command window:

cmd=testComplete&sessionId=260113

When this command finishes, your browser window should automatically close. To quit the Selenium Server, type "quit" or just press Ctrl-C.

When you look at the selenium Remote control page, they mentioned that you can do programming in any of the following language (php,perl, java, C#, python,Ruby). If you go to the following site, they gave scripts in different programming language.

http://selenium-rc.openqa.org/tutorial.html

Instead of knowing everything, let's understand with one programming language. I am assume that everyone would have learnt java in their college life and feel little comfortable in this language. So now we will take how to write our scripts in java and need to execute it.

Even if you don't know java , don't worry I will tell you how to get the scripts and need to execute it in available tool.

Selenium Java programming with Eclipse:

The first step is to get Eclipse.

Eclipse is a software platform comprising extensible application frameworks, tools and a runtime library for software development and management. It is written primarily in Java to provide software developers and administrators an integrated development environment (IDE).

In other words Eclipse is a software that allows you to write and execute programs in many different languages. In our case we will be using Eclipse to write and execute Selenium via Java.

Best of all Eclipse is a free software! (~Thank you Open Source)

Let us begin…

Getting Eclipse:Go to http://www.eclipse.org/downloads/

3. You will want to get Eclipse Classic 3.44. Click on “Windows” link to the right.

5. Now to download it, Click on the link that appears to the right of “Download from:”


http://www.eclipse.org/downloads/

http://selenium-rc.openqa.org/tutorial.html


6. Save the file.

After it has finished downloading, you need to extract the files to your D: driver directory.

In windows you would take the following steps:

3. Right Click on the zip file you just downloaded4. Click on Extract All...5. Click Next6. Click on Browser…7. Click on My Computer8. Click on Local Disk (D:)9. Click on OK10. Click on Next11. Click on Finish

At this point Eclipse is installed and ready to be used

Note: Keep in mind Eclipse is an “Executable” program; there is no installation need other than extracting the files on to your hard drive.

Now let us start up Eclipse…

Go to your C: driver and open up your Eclipse folder.

Double Click on Eclipse to run the program.

A Settings Window will open up letting you know that Eclipse saves your projects into a folder called “workspace.”



If you wish to change the location of this folder from it’s default location, Click on Browser… and choose your desired location.

If you do not wish to be informed about this again, Check the Box next to “Use this as the default and do not ask me again.”

Click on OK to continue.

Once Eclipse has loaded you will have the option to get an overview of the application, find out what is knew, review come sample codes, go through some tutorials, or go to your workbench. In our case, we want to go to the workbench, so click on the icon with the title “Workbench.”

This will bring you to the environment that you will be working in:



Our first step will be to create a Project*.

Go to FileClick on NewClick on Project…

At this point a new window has opened, here you will tell Eclipse what type of Project you want to create.

Click on JavaClick on Java Project

Click NextOn the top next to Project name: give your project the name “First”Click FinishNow you should be back at your work bench with your project’s folder visible to the left.



* A Project is basically what will save property setting of your environment and create a folder that will contain all the files you will be creating/using to accomplish your programming tasks.

The next step in the process is to import two Selenium Libraries, without them, you would not be able to run Selenium.

5. Right Click on the “First” folder6. Click on Properties

(Please note I crop the screenshots sometimes to a more appropriate size)

7. Click on Java Build Path8. Click on the Libraries tab9. Click on Add External JARs…

10. Find and select selenium-server.jar then Click Open (i.e. C:\selenium-remote-control-0.9.2\selenium-server-0.9.2\selenium-server.jar)

11. Click on Add External JARs… again

12. Find and select selenium-java-client-driver.jar then Click Open (i.e. C:\selenium-remote-control-0.9.2\selenium-java-client-driver-0.9.2\ selenium-java-client-driver.jar)



13. You should now see the two new JARs added to your Libraries list

14. Click OK

You have finished setting up your project to run selenium, now we create a class and write a simple Selenium program.

4. Right Click on First Folder5. Click on New6. Click on Class

At this point a new Window will open up

7. In the Name field give it the name MySelenium8. Click Ok

A new sub folder was created called “src” (short for source), and in this subfolder your class file was created called “MySelenium.java”

Further more your class file is opened up in eclipse and ready to be populated by code.



Lets try to run a simple Selenium program that opens of a Cafe express in Internet explorer.

Suppose if the user doesn't know java , no worries. Use selenium IDE and record the scripts.

Go to selenium IDE-> options->format-> choose Java-Selenium RC. Now you will be getting the following scripts in java format.

Step1: Open the mozilla firefox , I assume your homepage of the Firefox is http://www.google.com

Step2: Go to tools-> click SeleniumIDE

Step3: Now SeleniumIDE will open, minimize the Selenium IDE

Step4: By default, seleniumIDE opens in Recording mode

Step 5: Type the cafeexpress home page url, http://10.6.13.180/default.asp

Step 6: login to the cafeexpress, for someuser it will show session expired. Click the relogin link and move to the home page.

Step 7: click few links and do signout.

Step 8: Now if you go to Selenium IDE → Options → format → select Java-SeleniumRC , copy the scripts and paste it in Eclipse.

But usually the scripts won't be that much perfect like the following. Edit accordingly.

import com.thoughtworks.selenium.Selenium;import com.thoughtworks.selenium.DefaultSelenium;

public class MySelenium {

static Selenium browser;

public static void main(String arg[]){

browser = new DefaultSelenium("localhost", 4444, "*iexplore", "http://10.6.13.180/default.asp");

browser.start();


http://10.6.13.180/default.asp


browser.open("http://10.6.13.180/default.asp");browser.open("/index.asp?message=expired");browser.click("//table[@id='Table1']/tbody/tr/td/a/strong");browser.waitForPageToLoad("30000");browser.click("//table[@id='Table1']/tbody/tr[4]/td[3]/a/b");browser.waitForPopUp("eprintwinclose", "30000");

browser.selectWindow("name=eprintwinclose");browser.click("Submit3");browser.close();

}}

Supporting other tools:

Here we used eclipse for java and executed our scripts. There are many open source tools available in the market for supporting different programming language. We should know , which tool to use and how to use the tool.Here I am mentioning few supporting tools for SeleniumRemote control. They are

1. Bromine2. Cubic Test3. pyWinAuto4. Frankenstein5. Watir Recorder6. WET7. JTC



Save the file, and now before we run the program we need to start the Selenium Server.

8. Click on Start (Windows Start menu)9. Click Run10. Type cmd

This will open up the command window

11. Type in java –jar <location of your selenium-server.jar file> -multiWindow(i.e. java -jar C:\selenium-remote-control-0.9.2\selenium-server-0.9.2\selenium-server.jar -multiWindow)

The Selenium Server should be running now:

Now that Selenium Server is running in the background lets go back to Eclipse and run our program.

3. Click on Run4. Click on Run As5. Click on 2 Java Application

And you are DONE! Congratulations you have written your first Java-Selenium program using Eclipse.

Similarly you can get the scripts for other programming language from SeleniumIDE and run the scripts in Selenium Remote control.



Using Selenium RC With Multiple Users:

Additional information Selenium RC server on any port you wish, allowing multiple clients to connect at the same time.

To start the selenium RC server, you would typically run this command:java -jar selenium-server.jar

Which will start it on the default port of 4444. If you want to start it on another port, simply add -port <portnumber> to the command like this:java -jar selenium-server.jar -port 1234

This command would start the server on port 1234.

Great, now I can start the server on multiple ports, so what?So here is the good news for those of us in shared development environments. Say you have a windows virtual machine running selenium with your test browser installed. Things get complicated when multiple clients are testing at the same time. Tests can fail unexpectedly, developers begin fighting for time on the test server, and all hell breaks loose. By running multiple servers on different ports, we can avoid the third world war. Everyone can connect at the same time to their personal server, and we have peace and harmony in our testing environment.

User can even create a .bat file which is having the following code. So that selenium RC automatically starts running in different port.

start "Selenium 4444" /min java.exe -jar selenium-server.jar -port 4444start "Selenium 4445" /min java.exe -jar selenium-server.jar -port 4445start "Selenium 4446" /min java.exe -jar selenium-server.jar -port 4446start "Selenium 4447" /min java.exe -jar selenium-server.jar -port 4447

With this in place, we now have 4 selenium RC servers running at all times. If one or more crashes for any reason, running the batch file again will start any that are missing. The selenium RC server will not start if its port is in use, so only the ones missing will run, and you’ll have them all up and running again.

Ok, what about the client side? I don’t want to have to edit another file in my development environment. Suppose if you are using any programming language then you have to write your scripts in the concern language for execution.


http://www.zacharyfox.com/blog/testing/selenium-rc-multiple-users


For example:

If I am using php scripting language then I have to write my scripts in the code and need to open the selenium RC in different port.

Ex:<?phpclass SeleniumTestHelper{ public function setup() { $ports = array(‘user1‘ => 4444, ‘user2‘ => 4445, ‘user3‘ => 4446, ‘user4‘ => 4447); $user = someFunctionThatDeterminesUser(); define(‘BROWSER‘, ‘*firefox‘); define(‘URL‘, ‘http://www.example.com‘); define(‘SERVER‘, ‘192.168.0.2‘); define(‘PORT‘, $ports[$user]); $this->selenium = new Testing_Selenium(BROWSER, URL, SERVER, PORT); }}?>

Congratulation !!! now the user comes to know how to run the scripts in different port.

Remote Control. The other testing frameworks use Selenium Remote Control drivers for testing.

*** Using the appropriate driver (or HTTP commands), you can manipulate and test the browser using any testing framework by calling commands like "click" or "isElementPresent." Selenium Remote Control just deals with the commands and doesn't care about what actually calls those commands.

Conclusion:

There are n no. of open source tools available in the market. Each tool has it's own advantages and disadvantages. When it comes to open source tool contribution is very less. Obviously when you compare the opensource tool with the licensed version, the disadvantages may seen visible. But if the tester who is using the tool knows the tool end to end then he/she can able to handle any sort of situation successfully. Similarly selenium is also having it's own advantage and disadvantages but still people are using frequently shows that the tool is having something unique and useful to the IT organization. So learn and explore the tool thought it's useful now or not. The tools success is entirely depends upon the person who is going to use the tool. Selenium actually reached certain level of success in the market which really shows not only the tools features but also the people who used it in the right situation.
